Been wondering for years why the vast majority of DSLR users roll with a single neck strap instead of some kind of harness system? Is there something you all don't like about it... attachments? I'm no Ornitholigist, but one reason i use a rucksack is to let the D-rings and harness do the work ....Insert DSLR

Yes there is bounce but not so much the way i've adjusted the length and positioned those straps so field glasses or camera rests on the sternum. The overall pitch n yaw are greatly reduced and of course a DSLR/lens needs to be counter weighted by the ruck with more than just a sanga and can of lager
